I`ve got two problems . . .
1. I`ve crappy little scholastic piccalo that has had many better days. i got it second (or fourteenth) hand from my MS music teacher this summer. It used to be a school picc but for some reason it needed to be sold and now being in the HSMB I needed one. So i bought it and after a while of not getting anything out I can now play all but the F at the top of the staff and the E and E flat right below it. They sound very airing which is bad for my since we do this block thing where I have to hold an E natural for 3 4/4 measures. Any suggestions to fix my decrepide flute short of trahing it and buying a new one?
2. My band`s performing the Symphonic version of POtC in 3 weeks, before the holiday break and in it is a series of sxteenth notes that are played in a tempo called "Driving, with intesity" which translates to faster then the speed of light. Anyway my band directer showed us a way of seeing other then killing ourselves to try in play that the first time we saw it, if we can manage was to see we (flutes) could roll our "r"s. Now coming from a very northern heritage no one in my family speaks other my mother a language that u need to roll your Rs. My band director said it was a gentic thing but you can learn unlike "folding" and rolling your tongue, which I can do the latter of, is a form of genetics. And needless to say I can`t roll those Rs and now with the performance coming closer I still can`t tackle the duanting measures that hold these elusive rythms. In my own long winded way I`m asking, any suggestions to tongues these or at least learn to roll my Rs? I`ve tried Ta-ta-ka and the ta-ka-ta-ka.

The piccolo needs servicing by a person who is GOOD at doing piccolos. Check for a repairer with reputation first, with local, well-established teachers and players. Many `technicians` will make a piccolo worse! They can be difficult to work on. Ask if it is WORTH working on.

To try to explain how you could do something yourself would be quite pointless with a piccolo.
